How to Find out an Unknown Caller Number on iPhone?

Getting calls from unknown numbers is not always exciting but can be stressful too. The situation becomes more problematic when you get repeated scam calls from a hidden number. You always have the option to block them through the inbuilt feature of your phone, but it wouldn’t help you extract their details. This blog tells you how to find an unknown caller number on iPhone.

Hence, next time when you encounter an unknown number calling you, you can deal with it in a better way.

Let’s get deeper into the concept first. There are different types of situations when encountering incoming calls.

  • The number you cannot recognize or isn’t saved in your contact list comes under the Unknown number category.
  • On the other hand, when a call appears with an ‘unknown’ name, it means the caller has blocked you from seeing the number or has hidden their number.

These numbers may appear as ‘restricted number‘ or ‘No Caller ID‘. In both situations, you have the option to find out if it’s a spam number and block it.

How to find out an unknown caller number?

Here are the best tried and tested methods to find out unknown caller numbers on iPhone.

1. Go Online

This is one of the easiest ways to find out the details of an unknown number. If you can see the digits of a phone number, then type ‘reverse phone lookup‘ on Google. You can also try other websites like White Pages and AnyWho. It will lead you to related information.

When the result does not show anything, it may not be a spam number as you might have thought. Sometimes it may also show up as a company number. Note that you should still not be 100% sure that the company is trying to call you. Take your investigation deeper to confirm. However, if you see a forum of people discussing the scammy number, then it’s a clear red sign!

2. Apps

There are some applications to find out an Unknown Caller number on iPhone.

When nothing seems like working, third-party apps serve the best. There are various apps that can help you to catch the details of an unwanted caller ID.

Here comes a catch!

You should not pick any app randomly because different types have different capacities to tell you about the caller. Plus, most of them have payment plans, so choose according to your budget. Some of the most used and verified apps are –

  • BeenVerified
  • TrapCall
  • Spokeo
  • Truecaller, and more.

These are also geo-restricted apps, so check if you can use them in your country or not.

3. Dialing *69 or *57

You can dial *69 or *57 right after you have received a spam call to know its details. At first, you should try calling *69. It will tell you about the caller’s name and address if it is registered in the public database.

This option works well for anonymous and hidden calls too. You can use this information to call and verify the caller if you want. You can also choose to block the number.

It works well for not only iPhone but Android and landline users. It’s important to know that some phone companies also charge for this service, so it may deduct extra costs from your next bill.

In case someone is harassing you through calls, you can move on a step ahead and connect with law enforcement officials. Dialing *57 after getting a call from the scam number will help you reach them directly. They will track the number and take the necessary steps.

4. Facebook

This may sound strange, but Facebook can tell you a lot about the unknown number you have received. Simply type the number on Facebook’s search box, it will show the account linked with the phone number. In case the person has activated privacy settings, then you won’t be able to see the account.

5. Provider

Your phone company or telephone provider can help you know an anonymous caller’s details. They may give you the basic details but won’t disclose private details for privacy reasons.

6. Search Engine

Most people look up search engines to find any information. This is what you need to apply now. If you can see the digits of the calling number, copy and paste it onto the search engine directly. Press okay and see the results. There are few chances of getting any information about the unknown number unless it’s from a very reputed company, business, or brand.
